Give the temperature-volume law both in words and in the form
of an equation.
||How is the volume of a gas affected by a decrease
||What would be the new volume if the temperature
on 450 mL of gas is changed from 45oC to -5oC?
||A sample of gas whose volume at 27oC
is 0.127 L, is heated at constant pressure until its volume becomes
317 mL. What is the final temperature of the gas in Celsius and kelvin?
||To make 300 mL of oxygen at 20.0oC
change its volume to 250 mL, what must be done to the sample if its
pressure and mass are to be held constant?
||To what temperature must an ideal gas at 27oC
be cooled to reduce its volume by 1/3?
||From the data in the following questions calculate
the missing quantity.
a) V1 = 22.4 L; T1 = 0oC; T2 = 91oC; V2 = ? L
b) V1 = 125 mL; T1 = ? ; T2 = 25oC; V2 = 100 mL
c) V1 = ? L; T1 = 400 K; T2 = 175 K; V2 = 6.20 L
d) V1 = 250 mL; T1 = 298 K; T2 = ? K; V2 = 273 mL
||A 50 cm3 sample of a gas in a syringe
at 15oC is heated to 50oC and the syringe's piston
is allowed to move outward against a constant atmospheric pressure. Calculate
the new volume of the hot gas.
||What is the final volume if 3.4 L of nitrogen
gas at 400 K is cooled to 200 K and kept at the same pressure?
||Determine the final volume of 20 L of a gas whose
temperature changes from -73oC to 327oC if
the pressure remains constant.
||A partially filled plastic balloon contains 3.4
X 103 m3 of helium gas at 5oC. The
noon day sun heats this gas to 37oC. What is the volume
of the balloon if atmospheric pressure remains constant?
